Product Description


USB 3.0 for Fast Performance and Common Connectivity

Most drives available today include USB 3.0 interfaces. Although you can connect them to the USB 2.0 ports on your computer, their performance would be reduced by as much as 85 percent! This useful adapter offers native USB 3.0 support to ensure great performance from the fast drives you connect, enabling data transfers at up to 350 MB/s. Need to connect more than one drive? It works with multi-drive enclosureswith hardware raid controllers, too. This adapter also supports hubs and other USB 3.0 devices, and is backward compatible with USB 2.0 devices. If your computer already has USB 3.0 onboard, this adapter provides another handy port.

Gigabit Ethernet for Fast Wired Networking

GbE IconWith the introduction of new, thinner, lighter computers, manufacturers continue to remove ports that were once standard, including the RJ-45 connector for Ethernet, the standard wired networking interface. For many users, this leaves a connectivity gap. Connecting to a network via WiFi isn’t always desirable or practical, and may not be an option where only a wired network connection is available. Sonnet’s USB 3.0 + Gigabit Ethernet Thunderbolt Adapter instantly bridges the gap left by the missing onboard port, plugging in between your computer’s Thunderbolt port and the RJ-45 network connection, and enabling file access and sharing at up to 1 Gb/s.

This Sonnet adapter supports 1000/100/10BaseT auto-negotiation and full/half duplex communication, enabling it to easily connect with most networks at the highest performance transmission mode supported. It also supports jumbo packet transfers (9000 byte packets compared to 1500 byte standard packets) to provide higher performance and reduced overhead when transferring large files. Handy LEDs indicate network activity and link speeds at a glance. 

Simple to Set Up, Simple to Use

When used with a Mac computer, the USB 3.0 + Gigabit Ethernet Thunderbolt Adapter requires no driver installation—the necessary drivers are already installed—just plug it into your computer and it works. When connected to a Windows PC, a simple Ethernet driver download and installation is all that’s required to get you going. Setup is simple—configure the adapter settings through the OS X Network control panel or Windows® Device Manager.

This device is bus-powered, so there’s no need to connect an AC power adapter, making it perfect for use anywhere. Wherever you use it, the Sonnet USB 3.0 + Gigabit Ethernet Thunderbolt Adapteris a simple and cost-effective solution that enables you to connect your USB 3.0 peripheral and get connected to a wired network at the same time, without hassle.
